Which of the following chemicals used in the Perioperative Department is considered non-carcinogenic?

Monsel's solution, primarily composed of ferric subsulfate, is used in the perioperative setting, particularly for its hemostatic properties during surgical procedures. It is considered non-carcinogenic, meaning it does not have the potential to cause cancer in humans, making it a safer choice for use in clinical environments.

In contrast, other options represent substances with known risks. Polymethylmethacrylate can present toxicity and other health concerns, particularly when its dust is inhaled. Formalin, used as a disinfectant and preservative, contains formaldehyde, which is classified as a carcinogen. Ethylene oxide, while effective as a sterilizing agent, is also recognized as a carcinogenic risk. Understanding these distinctions is crucial for maintaining a safe environment in the perioperative department.
